MARTIN o. REHFUss AND JOHN GEORGE REHFUSS, or PHILADELPHIA, PENNSYL- VANIA, 'ASSIGNORS TO THE CURTIS PUBLISHING COMPANY, -PENNSYLVANIA, A CORPORATION OF: PENNSYLVANIA.

]? PHILADELPHIA,

Application filed May 22 Be it known that we, MARTIN O. REHFUSS the United States, and residents of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have jointly invented a certain new and useful Package-Twine- Fastening Machine, of which thefollowing V is a specification.

The present application covers a portion of themachine shown and described in our Patent No. 1,164,548, granted Dec. 14:, 1915, together with improvements- The principal objects of the present invention are to provide efficient and' reliable mechanism for clenching a staple around the twine with which a package is tied, so as to firmly secure it; to "provide the mechanism 1 with eflicient means formaking the staples from alength of wire intermittently fed to the machine; to provide for properly presenting thetwine to the stapling mechanism in such a way that the staple can .be reliably clenched around'the twine; to providefor cutting the cord or twine in a plane at rlght angles to itself, so that its end will be in proper condition to permit of its. belng threaded, and t rovide a machine for automatically clenc 'ng a staple around a twine or cord which encompasses a package in such a way that the fastening is tight and-the outside of the package or paper applied thereto is not marred or disfigured.

The invention will be claimed at the end hereof, but will be first described in connection with the'embodiment of it chosenfrom' among other embodiments for illustration in the accompanying drawings, in which- Figure 1, is a front view, partly in section, of a machine. embodying features of the invention with parts thereof omitted in order to illustratemore particularly the. stapling mechanism. Fig. 2, is aside view, partly in section, of Fig. 1. Fig. 3, is a top or plant view. Fig. 4,-is a perspective view showing.- .the stapling mechanism as viewed from the rear. Fig. 5, is a view'similar to Fig. 4 showing another position of the parts. Fig. 6, is a view of the stapling and cutting mechanism taken from the rear; that is, looking in' the direction of from the top to. the bottom of the sheet in Fig. 3. Fig. 6 is a detail view illustrating'a feature of operation. Fig. 7, is a sectional view showing the Specification of Letters I'ateht.

I 'mechanism illustrated in. Fig. "6. Fig. 8, is

an enlarged view of the package, and Fig. 9, 1s a detached view of the staple.

In the drawings 1 is a power shaft and it is a convenient source of power for the counter-shaft 2 which operates the mechanlsm about to be described. Rising from the bed or frame 3 of the .machine is-an overhanging head 4. The package m is presented beneath this head with the cord or'twine 3 wrapped around'it and crossed as shown in Flg. 8; the ends 6 and e of the cord ortwine being held in the position shown in Fig. 8. f The means whereby this is accomplished are .fully disclosed in our application above referred to andneed not be described here and the facts mentioned are recited merely to facilitate an understanding of the present invention.

()n the face of the head i are arranged two slides 5 and 6. These slides are'each movable with respect to the head and the one in f'respecttothe other. As shown the slide 5 works in ways in the head 41 andthe slide 6 works in ways in the slide 5.

7; and 8 are a'pair of jaws pivoted at 9 to the slide 5, and the ends of these jaws. are

jaws in open and closed position and by shifting the slides with respect to each other it is possible to open and close thejaws. The slides are worked inithis way byv means of Jmechanism which will now be described.

Referring to Fig. 4 on the back of each slide'there is a rack 12 and for each rack there is a toothed sector 13. These sectors are mounted on shafts 14 and'15' sle'evedto gether. At the end of these shaftsa're crank arms 16 connected by links l'f with the piv- ,otal followers of the grooved cams 18and19.

and driven by gearing'22 from the counter- 23 so that while they run continuously they 20. and 21. are feed rolls geared together 1 feed "the wire 24 intermittently. The wire is'fed through a guide 25, Fig. 6, over an an'-.

vi127 and -under a holder 28. Both the anvil 27 and the" holder 28- can be projectedand withdrawn with respect to theface of 4 the head 4. I This is accomplished by arms 29 on shafts 30 which are operated by grooved cams 31 on the shaft 2, through the intervention of links 33. The edge 34 of the arm 8 operates as a cutter when it passes a link 38 with a bracket 39- attached to the "slide 5 so that the movement of the slide causes the fork to swing about its center into the position shown in Fig. 4 and into the position shown in Fig. 5 where it underlies the twine 0r cord y, lifting the same from the package or the wrapper of the package into position for receiving a clenched staple.

40 and 41, Fig. 6, are cutters pivoted as at 42 to a bracket carried by the head 4.

It may be said that the jaws 7 and 8 work in the plane of the dotted line a a in Fig. .8, and that the cutting jaws work in the plane of the dotted line bb in Fig. 8, so

, that the cutting jaws and stapling jaws are in planes at an inclination with each other. This is due to the fact that the staple is placed crosswise of the crossed tWlIlG or cord. The end e of the twine or cord should be 'cut straight across so as to leave its end in condition to be threaded through some appropriate piece of machinery, not material to this case. There is a tappet arm 43 which operates upon a spring-pressed tappet rod 44 to which the. shanks of the cutting jaws 40 and 41 are pivoted by links 45.

- 46 are guides for the ends of the jaws 7 and 8. v

47 shows the staple clenched with'its ends overlapping and. this overlapping is produced by the shape of the working parts 48 of the stapling jaws? and 8.

A description will now be given of the mode of operation of the machine. The package w is in the position indicated in the various figures and the ends e, 6 of the cord are held in the position shown in Fig. 8. The wire is fed so as to lie between. the anvil 27 and the holder 28. The part34'of the jaw 8 cuts the wire off and the jaws 7 and 8 bend the wire around the anvil 27 in the form of an open ring in Fig.- 6 the part 34, of the jaw 8, or more accurately, the lower right-hand corner of that jaw shown in section is about "to cut oif the wire 24, when the jaw is descending. It will be understood from that figure that the part 34 lies behind a laterally projecting flange which is broken away in Fig. 6 The anvil and holder are then withdrawn leaving the partially made staple held between theends of the jaws 7 and 8. The jaws 7 and 8, carrying the open staple, descend in the plane of the line wa,

Fig. 8, putting the staple across the cord or twine and clenching it with its ends crossed, as shown in Fig. 9. These various movements are brought about by the mechanism which has already been described, which includes the movement of the movable slides 5 and 6. The movement of these slides also causes the lifter 35 to get in under the twine orcord as shown in Fig. 5, and so lift it up into position for receiving the staple. The movement of the slides also closes the cutters 40 and 41. and cuts the cord on the line 5-4) of Fig. 8. In this way the staple is very tightly applied tothe cord or twine so that the latter is very firmly held. The surface of the package or the wrapper around it is not torn or marred and the cord or twine iscut off in such a way that it can be readilythreaded as in preparation for tying additional packages. Additionally the staple is made in the course of the operation from a length of .wire and is, it might be said, in the making properly placed in'the stapling jaws. The operations described are repeatedly and satisfactorily performed and the mechanism is simple and positive in action. The end of the wire 24, may butt into the left-hand side wall, Fig. 1, of the ways in the head 4, in order to help measure off a proper length of wire for a staple, or a spring retracted stop 49, Fig. 6, may be 6H1- ployed. This stop 49, is pivoted as at 50 and normally held by a spring 51 against a stop pin 52 in the line of feed of the wire 24, so that when the end of thewire strikes it the wire cannot be fed farther but may slip in the rolls 20 and 21. lVhen the stapling jaws descend, the jaw 7 pushes and turns the stop 49 out of its way.

It will be obvious to those skilled in the art that modifications may be made in details of construction and arrangement hence the invention is not limited to those matters nor to the precise embodiment of it selected for illustration, nor is the invention limited in any way further than the prior state of the art and the appended claims may require.

What we claim is:

1. In a package twine fastening machine the combination of stapling jaws adapted to .clench a staple around the crossed twine, a twine lifter independently movable with respect to all said jaws and adapted to pass between the package and its crossed twine to lift the latter into range of the staple, and means for operating said parts including mechanism for moving the lifter with respect to all the jaws, substantially as described. v
